Researchers originally thought that men who were balding must have fewer of the necessary stem cells that produce hair. They were stunned to learn that the number of cells in bald men was actually the same as in men with full heads of hair.

"We were surprised to find a totally normal number of stem cells in the hair follicles in the bald scalp," Dr. George Cotsarelis, the chairman of the dermatology department at the University of Pennsylvania said. "So this raised hope to people that we can come up with a way of activating these stem cells."

Scientists say, with those stem cells in the scalp already, all that needs to happen is to get those cells to produce the secondary cells that produce hair.

Stem cells produce progenitor cells, or so-called workhouse cells.

"If we figure out a way to wake up those stem cells, get them to make hair for progenitor cells, that would go a long way toward developing a treatment," Dr Cotsarelis told ABC News.

Researchers predict they'll be able to do that within a decade. But until then, millions of customers will be left waiting, and spending.

An estimated $3.5 billion is already spent on hopes for new hair such as Rogaine and Hair Club for Men.

This is no surprise, considering a man has a 50 percent chance of experiencing hair loss by his 50th birthday.
